Ceiling types include conventional ceilings, suspended ceilings and high-sloping cathedral ceilings. These can be built out of a variety of materials, but the most common are drywall, wooden panels and various types of tiles.
Conventional ceilings are the simplest type. They are typically made of the same material the building's interior walls are, then covered in drywall or plaster. Conventional ceilings are limited by size, as constructing such a ceiling to be larger than 10 feet high requires the use of specialized construction materials.
Suspended ceilings, also called drop ceilings, consist of a metal grid hung from the existing ceiling of the joists of the floor above. Then, panels are installed into the spaces marked by the metal grid, allowing wiring and plumbing installations to be effectively hidden above the false ceiling.
Cathedral ceilings attach directly to the building's roof trusses and extend to the very top of the building. This ceiling type makes a dramatic architectural statement but offers problems to property owners, especially when painting, switching light fixtures, or attempting to heat or cool the building's interior.
Of all the materials ceilings tend to be made out of, drywall is the most common. Drywall is typically white and flat, but can be painted. Ceiling tiles are usually attached using tracks and clips, glue or nails.
